“Again you have heard that it was said to those of old, ‘You shall not swear falsely, but shall perform to the Lord what you have sworn.’ But I say to you, Do not take an oath at all, either by heaven, for it is the throne of God, or by the earth, for it is his footstool, or by Jerusalem, for it is the city of the great King. And do not take an oath by your head, for you cannot make one hair white or black. Let what you say be simply ‘Yes’ or ‘No’; anything more than this comes from evil.”
In His sermon on the mount, Jesus does quite a bit of unpacking of the 10 Commandments. As sinful people, the people of Israel (like all of us) had taken the 10 Commandments and done two things with them.
So, for example, you could hate your brother and harm him in certain ways, but not kill him and you’ve still followed the 5th commandment.
In today’s passage, Jesus is dealing with the 8th Commandment not to lie. One phrase that has always amused me is when people have been talking to you for a while and then they start a statement with,
“To be completely honest…”
What? Have you been lying to me up until now?
Speak the Truth
Jesus approaches the commandment in a simple, but perhaps surprising way. He says not only should you not swear falsely (lie), but you shouldn’t take an oath at all.
Some people have taken this passage to mean they can’t take the oath at the beginning of a legal testimony, but that’s not what Jesus is getting at. What he’s saying is, just be honest. If you don’t lie or bend the truth, but simply be honest, there’s no need to take an oath.
The oath is said to either prevent lying or to give the impression that someone isn’t lying. But if you make a habit of telling the truth, you won’t need that. You won’t need the extra element of an oath to convince people you are telling the truth if you are known for telling the truth. They will rightly believe you.
Interestingly, psychologists will tell you that when someone starts a sentence with something like, “To be completely honest…” there’s a very good chance they are about to lie to you.
Speak the Truth in Love
It has to be said that the Bible also tells us to speak the truth in Ephesians 4:15, but adds that it should be done in love.
The truth can be used as a weapon. It can be used to harm and destroy rather than heal and built up. We are to always speak the truth, but we are also to show love to each other. If a friend were to come to me in confidence and confide in me about a struggle they were going through, I could go tell everyone what they told me and be speaking the truth, but I wouldn’t be showing love.
Similarly, how we say the truth matters. The Bible says that we should be gentle.
Love is to govern all that we do, including speaking the truth. That means considering the time, people, place, tone, and purpose of how we speak the truth to be sure it is done in a loving way that heals, protects, is just, and builds each other up in Christ.
This is how God deals with us. He tells us the truth in love. His Law reveals our sin, which can be difficult to hear, but He also gives us His promises of forgiveness, salvation, and eternal life. Both are true and both are loving.
Let’s pray…
Heavenly Father,
Thank You for the truth of Your Word. Gently reveal my sin to me in order to lead me to repentance. Also, comfort me with the truth of your wonderful Gospel promises. Help me to treat others the same way, to always speak the truth and do so in love. Please, also give me the wisdom to when, how, and to whom I should share truths.
Amen.
As part of your devotion time, I encourage you to also pray for at least some of the following:
After praying for these people, you may want to finish your devotion time with the Lord’s Prayer…
Our Father, who art in heaven, hallowed be thy name. Thy kingdom come. They will be done, on earth as it is in heaven. Give us this day our daily bread and forgive us our trespasses as we forgive those who trespass against us. Lead us not into temptation but deliver us from evil. For Thine is the kingdom and the power, and the glory, forever and every. Amen.

In Christ’s Service,
Pastor Kurt
